SIGHT FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 783,540, dated February28, 1905.

Application filed February 29, 1904. Serial No. 195,914.

To aZl wlwm, it may concern: I

Be it known that I, EDwINSYLvEsTnR PRATT, marine engineer, of ParrySound, in the district of Parry Sound, Province of Ontario, Dominion ofCanada, have invented certain new and useful Improvements in Sights forFirearms and the Like, of which the following is a specification.

My invention relates to improvements in sights for firearms and thelike; and the objects of my invention are to devise a sight which may beadjusted to suit various conditions of light and atmosphere and also tosuit the person using the firearm; and it consists, essentially, of abase adapted to be secured by any suitable means to the barrel of thefirearm, bearings integral with the base supporting a spindle which islaterally disposed relative to the axis of the barrel andislongitudinally slidable in the bearings, a sight-wheel mounted on ahub rotatably mounted on the spindle, said sight-wheel having aplurality of sights of various kinds thereon, which might be broughtinto position for use as desired, the various parts being constructedand arranged in detail as hereinafter more particularly described.

Figure 1 is a perspective view of the end of the barrel of a rifle,showing my adjustable sight secured thereto. Fig. 2 is a side elevation,slightly enlarged, of the adjustable sight. Fig. 3 is a sectional planof the attachment, taken on the line 3 3, Fig. 2. Fig. 4 is a plan viewof the attachment. Fig. 5 is a perspective view of the sight-wheel andhub.

In the drawings like letters of reference indicate corresponding partsin each figure.

a is the sight wheel or disk. This disk is provided with four or more orless sights I) of difierent colors and shapes, which are adapted for useunder different atmospheric and other conditions. The disk (4 is furtherpro- Vided with a hub 0, to which it is secured or spindle (Z protrudesslightly beyond the end of the bearing f.

The outer end of the hearing a is closed, thereby forming a backingagainst which the spring y presses, the other end of the said springbeing adapted to-bear against the end of the spindle d.

h is a pin which extends transversely through the center of the spindled. This pin normally is pressed into transverse slots formed in theleft-hand face of the hub c, and is at the same time partly engaged byslots 1', formed in the sides of the bearing c, and it will thus be seenthat the sight-disk and hub are prevented under normal conditions fromrotating. By exerting a pressure on the'end of the spindle tithe pin 7twill at once be moved back into the slots so as to clear the slots inthe hub, and thus the hub and disk will be free torotate, and the usermay rotate the hub till the sight is brought into position, and then thepin may be permitted to spring back into the slots '21 2', so as to holdthe hub and disk in the position to which they have been adjusted.

It may here be mentioned that the bearings c and f are integrallyconnected together by a suitable base k, which is adapted to slide intoadovetailed groove l in the barrel on or to be otherwise securedthereto.

It will now be seen that I have invented a device which will be of greatassistance to sportsmen and users of rifles and other firearms ingeneral. It is also to be noted that my device for adjusting the sightsis extremely neat and simple in operation. I may use any suitable coverto protect the sights, .the one shown as fitting into the side grooves abeing for purposes of illustration only.

It is to be understood that I do not wish to limit myself to theidentical construction herein shown and described, as the device issusceptible of variations in detail without departing from the spirit ofmy invention.

What I claim as my invention is 1. In adevice of the class described thecombination with the disk and the-plurality of sights secured thereto,of a hub secured to the disk, a spindle upon which said hub,is rotatablymounted, said spindle being supported in bearings one end thereofprotruding beyond the end of one of said bearings, a pin extendinglaterally through said spindle, slots formed in the adjacent faces ofthe hub and one of the bearings and spring means for causing said pin tonormally engage a slot in the hub and the slots in the bearing therebyholding the hub from rotation and permitting the hub to rotate when thespindle d is pressed inwardly thereby disengaging the pin from the slotsin the hub.

2. In adevice of the class described the combination with the disk andthe plurality of sights secured thereto, of a hub secured to the disk, aspindle upon which the hub is rotatably mounted, bearings for saidspindle, one of said bearings having a spring therein abutting at oneend against the end of the bearing and at the other end against the endof the spindle, the other end of said spindle protruding beyond the endof .the other bearing, a pin extending laterally through said spindle,slots formed in the adjacent faces of the hub and one of the bearings,the ends of said pin protruding beyond the sides of the spindle beingadapted to normally engage one pair of slots in the hub and the slots inthe bearing and means whereby pressure on the protruding end of thespindle Will disengage said pin from the slots in the hub therebypermitting the hub and sight-disk to rotate as and for the purposespecified.

Signed at Parry Sound this 24th day of February, 1904.
